The lawsuit alleges that House Bill 1595, by Sen. Todd Lamb, R-Edmond, and Rep. Dan Sullivan, R-Tulsa, covers more than one subject and thus violates the Oklahoma Constitution.

The measure requires physicians to provide detailed information to the Oklahoma State Department of Health about the abortions they perform.

Information to be reported by the physician performing an abortion includes age, marital status and education level of the woman; number of prior pregnancies; reason for the abortion; method of the abortion and payment; type of medical health insurance coverage; cost of the abortion; whether an ultrasound was given; and nature of the mother's relationship with the father.

The suit alleges the bill covers four subjects, including redefining a number of abortion-related terms used in state law; banning sex-selective abortion; reporting requirements; and new duties for the Oklahoma State Department of Health, State Board of Medical Licensure and Supervision, and State Board of Osteopathic Examiners.

"We will be reviewing the lawsuit over the coming days and will respond to the claims appropriately," said Charlie Price, a spokesman for Oklahoma Attorney General Drew Edmondson.
